Table 1 pavement structural depth and cornering ratio testing result
| Construction technology | Construction depth (mm) | Cornering ratio SCF 60 |
| Former road surface | 0.22 | 35 |
| |
0.65 | 55 |
| |
0.71 | 58 |
| The comparative example 1 | 0.18 | 28 |
The comparative analysis of result of the test:
Existing " bituminous pavement design for highway standard " (JTG D50-2006) requires asphalt pavement of highway to hand over when checking and accepting, and the construction depth of surface course is not less than 0.45mm; Cornering ratio SCF
60Be not less than 45.By as seen from Table 1, after this speedway was open to traffic 5 years, pavement skid resistance condition descended, lower than code requirement.
Adopt existing mulseal " mist seal " technique, further reduced pavement structural depth and cornering ratio, weakened pavement skid resistance condition, threaten traffic safety.
And the construction technology that after employing spread mulseal of the present invention, Spurs rolls, more than construction depth and cornering ratio all return to the design specifications required standard.Therefore, construction technology of the present invention had both been sealed the crack of road surface, had improved again the cling property on road surface.
